Enum ActionMapError 

pub enum ActionMapError {
    DuplicateName(String),
    UnknownAction(String),
    UnknownContext(String),
    ContextAlreadyActive(String),
    ContextNotOnTop(String),
    InvalidDeadzone(String),
    NotAButton(String),
    EmitsItself(String),
}

What can go wrong when mutating an ActionMap.

Variants

DuplicateName(String)

An action with this name is already declared.

UnknownAction(String)

No action with this name has been declared.

UnknownContext(String)

No context with this name has been declared.

ContextAlreadyActive(String)

ActionMap::push_context was asked for a context already active — GAMEPLAY_CONTEXT and GLOBAL_CONTEXT always are.

ContextNotOnTop(String)

ActionMap::pop_context was asked for a context that is not the topmost pushed one — GAMEPLAY_CONTEXT and GLOBAL_CONTEXT are never pushed.

InvalidDeadzone(String)

A Binding::PadStick’s dead zone or a Binding::PadTrigger’s threshold on the named action is not finite and in 0.0..1.0.

NotAButton(String)

ActionMap::set_emits was asked to make a pattern emit an action that is not an ActionKind::Button.

EmitsItself(String)

ActionMap::set_emits was asked to make a pattern emit the action it is attached to.

Trait Implementations

impl Clone for ActionMapError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ActionMapError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ActionMapError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ActionMapError

impl Error for ActionMapError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ActionMapError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
